Messages

First about ICMCC

• The ICMCC Community will make

a difference

• Building Capacities

• Sharing Global Knowledge

• Patients

• Providers

• Payers

• Projects

• Source of Excellence & Innovation

• Incubator for ideas and projects

• Second about Health Care ICT

• Just when you think you have

developed the perfect IT solution

something change

• Source be for ICT knowledge?


Lets return to PH IT

The Perfect Solution?

Example Public Health IT Applications

Evolution

Use of standards & tools

Public Health Information Network

(PHIN)


Immunization Tracking Systems

• 2 nd Population based

registries

• 1 st Vital records

• Driven in 1993 by a

desire to improve

immunization rates

• IT evolved from Client

Server to Web-based

based

• Early standards work

• Date Elements and

security


Communicable Disease

Reporting Before 9-119

>80 Notifiable disease

reports

Case Mgt. at local

level, individual tools


Communicable disease Reporting the

Next Generation of ICT

New Focus – timely and accurate

Electronic exchange

Standardized data

Use of latest IT

Web, HW, SW,

Tools, Flexible

• Also all notifiable

diseases

• Bioterrorism

• Smallpox

• Anthrax


Public Health ICT for

Communicable Diseases

1. Early warning of outbreaks

2. Accurate reporting of disease data

3. Information based decision tools to

support outbreak management

4. Evaluation of actions to enhance future

responses

Public Health Information Network

• Designed to create standard

architecture for information sharing

• E-health of public health

• 2002 began in U.S.

• Standards groups specific to

• Messaging

• Electronic exchange (Health Level 7 - HL7)

• Data standards for lab and disease reporting

• INTEROPERABILITY!

changes in incoming data)


Outbreak Management,

Contact Tracing and Case Investigation


Just when we thought we had a

good system

China SASR Cases Map 5-18-03


SARS 2004: China CDC Institute of Virology

1 st case: 4-22-2004

9 cases up to May 20 th

1 death.

First 2 cases from NIV.

NIV closed 4-23.

Computer donation?

Was there a source for ICT? NO!


Case Investigation and

Vocabulary Inconsistencies Problem

for Epidemiologists

• Changing Questions i.e. SARS

• "Have you visited Hong Kong in the last 10 days?“

• Followed 2 days later by "Have you visited Hong Kong

or Guangzhou Province in the last 10 days?“

• Followed 3 days later by "Have you visited Hong Kong,

Guangzhou Province, Hanoi, or Bangkok in the last 10

days?“

• Again followed a few days later by: "Have you visited

Hong Kong, Guangzhou Province, Hanoi, Bangkok, or

Toronto in the last 10 days?"

New Tools Were Required to Support Emerging Disease

Case Management…Was there a source of knowledge?

No!! There was not even a source of Epidemiology

knowledge in the disease

A Movie

• ICT in a Changing Environment

• How an Immunization Tracking

System is Now used to Support

• Outbreak Management

• Emergency Preparedness

And will still support the primary mission


Conclusion

• Applications in Health Informatics May Address a Well Defined Problem but

Expect Change

• It is also impossible to plan for every future requirement

Therefore:

• Where will be the knowledge base be to support Health informatics s dissemination

of information?

• Where will others go for lessons learned and new technologies?

• Where will research and innovation in ICT be centered?

• Where will results of medical and health IT advancements be shared?

It will come from the contributions of the global members and resources of the

ICMCC. We have the opportunity to make a difference. We have the opportunity

to impact the quality of life by undertaking the challenges offered in patient

Medical and Care Compunetics.
